7TM5 — Sorghum bicolor

Summary

SORBI_3005G144201 (symbol Sb7TM5) on sorghum chromosome 5 encodes a GOST seven transmembrane domain-containing protein belonging to the GPR107/GPR108-like family. This gene is associated with positive regulation of cellulose anabolism, membrane organization, protein localization to the plasma membrane, and GPCR signaling pathway. The encoded product localizes to the Golgi cis cisterna, trans-Golgi network, Golgi complex, membrane, and plasmalemma. Studies of related genes in other species link the family to leaf number, plant height, cold tolerance, seed germination, and reduced hypocotyl growth with thicker hypocotyls and reduced cellulose. No phenotype was detected under stress screening in this species.
